The mixers are normally mounted over stainless steel guiding assembly and can be freely adjusted on these or lifted out of the water for maintenance. Submersible mixers are equipped with an IP68 rated motor and stainless steel propellers.įor power ratings up to 2.2 kW, the propeller is driven directly by the motor, and beyond that by a planetary gearbox housed in the pressure-tight casing. Sealing is achieved by means of mechanical seals. The motor housing is normally made of cast iron, but can also be supplied in stainless steel. In the industrial sector, they can be used in all cases where either settling of solids is to be prevented or directional flow is to be maintained. In the wastewater treatment sector, for example, they are used to prevent settling in retention basins, larger pumping stations, or for mixing in sludge storage tanks. The rotating impeller generates velocity and the casing converts velocity into flow. Submersible mixers are used to create horizontal flows for mixing liquids in various basin shapes.ĭue to the wide power range and different mounting options, they can be applied in almost all cases where mixing of a basin is required. Centrifugal pumps are made up of two primary components: an impeller and a casing.
